Embodiment 1

[0007] Embodiment 1, a kind of high-efficiency waterproofing agent for construction, is formulated by the following components by weight percentage: ultrafine mineral powder 20%, coconut oil 40%, surfactant 5%, calcium hydroxide 12%, polycarboxylate Water agent 2%, sodium silicate 3%, antiseptic slow release agent 1%.

Embodiment 2

[0008] Embodiment 2, a kind of building high-efficiency waterproofing agent, is formulated by the following components by weight percentage: ultrafine mineral powder 30%, coconut oil 30%, surfactant 8%, calcium hydroxide 5, polycarboxylate water reducing agent 2.5%, sodium silicate 2%, anti-corrosion slow-release agent 5%.

Embodiment 3

[0009] Embodiment 3, a kind of high-efficiency waterproofing agent for construction, is formulated by the following components by weight percentage: ultrafine mineral powder 25%, coconut oil 35%, surfactant 6.5%, calcium hydroxide 8.5%, polycarboxylate Water agent 2.3%, sodium silicate 2.5%, anti-corrosion slow-release agent 3%.

[0010] The preparation method of the water repellent is to weigh a certain amount of natural coconut oil and put it in a reactor according to the above embodiments, heat it to 150 degrees for 20 minutes, and successively add surfactant, diluted calcium hydroxide, and polycarboxylate to reduce water. Continue to heat and heat up to 100 degrees, the reaction is complete in 1.5 hours, add tap water to dilute to the required concentration, cool down and fill in barrels for later use.

Abstract

The invention relates to the technical field of the fine chemical engineering, and concretely relates to a high efficiency building water repellent. The water repellent is prepared by using 20-30wt% of ultrafine ore powder, 30-40wt% of coconut oil, 5-8wt% of a surfactant, 5-12wt% of calcium hydroxide, 2-2.5wt% of a polycarboxylate superplasticizer, 2-3wt% of sodium silicate and 1-5wt% of an anticorrosive sustained release agent. The high efficiency building water repellent provided by the invention has the advantages of construction convenience, environmental protection and safety.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a high-efficiency waterproofing agent for buildings. Background technique [0002] At present, both new and old buildings in China are leaking and seeping. Capillary pores, settlement gaps and shrinkage cracks in concrete components are the main water seepage channels. Waterproofing agent has the functions of water repellency, waterproofing, increasing the fluidity of concrete, easy pumping, micro-expansion, and plastic preservation. Therefore, waterproofing agent is the main material for improving and preventing concrete water seepage. However, the currently used concrete waterproofing agent has poor acid and alkali resistance, has a pungent odor, and is prone to cracks when it is poorly maintained. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a kind of high-efficiency waterproofing agent for construction, which is convenient fo...
